-Be itknown thatI, Is'nA which the following is a specification.

ing means for causing the liquid to percolate through the coffee above the liquid in the pot, and an object of my invention, among others, is to provide a device of this class in which the action shall be particularly quick and effective.

One form of device embodying my invention and in the construction and use of which the objects herein set out, as'well as others, may be attained, is illustrated in j phragm 21. The fountain tube 7 is secured the accompanying drawings, in which- Figure 1 1s a side view, partially in central-vertical section, of a coffee pot embodying my invention. Fig. 2 is a detail view on enlarged scale partially in central section through the fountain showing its construction. Fig. 3 is a detail top view of the fountain with the cap removed.

In the accompanying drawing the numeral 5 denotes a coffee pot, that may be composed of any suitable material and that may be of any desired shape. This pot has a depression 6 at the bottom thereof forming a recess within which the fountain is located, a fountain tube 7 projecting upwardly from the fountain to deliver the liquid from the pot on to a body of cofiee located in a basket 8 supported in any suitable manner within the pot, the latter being closed as by a cover 9. All of the parts above mentioned, with the exception of the fountain, may be of any well known construction and further and detailed description is therefore omitted herein.

The fountain 10 is preferably of a form to fit the recess ll in the depression 6, and

it is constructed to provide a heating chamber 12 at the bottom of the recess 11. As herein shown the outer surface of the bottom of the fountain is made concave to form the heating chamber, the interior of the fountain having an insulating chamber 13 located within the base 14. This base may be formed in any suitable manner, as herein shown, a cap 15 being secured to the top of PERCOLATING COFFEE-POT.

Specification of Letters Patent.

Germs, a "citi-. zen. of the United'States, and-a resident of Meriden, in thecounty of New Haven and State of Connecticut, have invented 'a'fnew and. Improved Percolating Coffee-Pot, of:

g the dishfishaped body lfi. A neck 17 rises from the base of the fountain and in that neck an inlet chamber 18 is formed at one side thereof having an inlet opening 19. A valve chamber 20 is also formed in the neck '17 above a diaphra m 21 extending across theneck, in the preferred form of construction, a cap 22 closing the top of the neck and constituting a part of the valve chamber 20. A passage 23 extends from the heatmg chamber 12 into the valve chamber 20 and a valve opening 24 leads from the inlet chamber 18 into the valve chamber 20. A valve 25 is pivotally mounted to control the opening 24, in the preferred form of construction, and as shown herein, this valve inany suitable manner to the cap 22.

In the operation of the device, heat being applied to the bottom ofthe pot, the liquid .within the heating chamber 12 is quickly heated to a point to provide sufi'lcient prespassage 23, the valve chamber 20 and the tube -7 at the upper end of which it is discharged. This pressure closes the valve 25 against its seat, and as soon as the pressure is relieved the valve 25 rises and allows the liquid to enter the inlet opening '19, the inlet chamber 18, and passing through the valve opening 24 into the chamber 20 it flows through the passage 23 to the heatin chamber 12 where the action is repeated. be construction is so simple as compared with percolators in common use that it may be made at a comparatively low cost, and yet the operation is more effective than that of some expensive and complicated structures. The arrangement of the pivot is such that the valve may readily respond to pressure at any point, and it is extremely sensitive for this reason.

While I have shown and described herein a preferred form of device for carrying out my purpose, this may be changed to a reater or lesser degree and yet embody the mvention, and I do not therefore limit the invention to a device made in exact accordance with that herein shown and described.

I claim-- 1. A percolator including a vessel, a desure to force the liquid upward through the nun-rvice constructed-to'formthe top of a-heating chamber at the bottom of the vessel, a neck rising from the top of said device and having a closed top, a fountain tube opening into the neck, a diaphragm extending across the neck, a valve chamber above said diaphragm and. an inlet chamber below it, the said diaphragm having a valve opening and an opening to a passage to the heating chamber, said neck having an opening in its side wall to said inlet chamber, and a valve pivotally mounted on saiddiaphragm tocontrol flow through the valve opening.

2. A percolator inc vice formed to provide a heatin chamber at the bottom of the vessel, said evice'having a neck rising therefrom, a cap removabl secured to-the neck to close the top there'o a fountain tube rising from said-cap, a diaphragm extending across the neck and constituting a boundary ofa valve chamber above and an inlet chamber below said diaphragm, the said diaphragmhaving a valve opening and an opening to a passage communicating with the heatingl chamber,

said neck having-an opening t rough its side wall communicating with the inlet chamber, and a valve pivotally mounted upon said diaphragm to control flow through the valve opening.

3. A percolator including a vessel, a tonne.

- tain located in the bottom of the vesseland constructed to form the top of aheating' chamber at the bottom of the vessel, said fountain having an insulatin chamber, a neck rising from-thestop of te insulating chamber, said neck being c'losedat its top, a fountain tuberising from the top of the neck, a diaphragm extending across the neck forming a boundaryof a valve chamber above and an inlet chamber below said diaphragm, the said diaphragm having a. valve opening and an opening to a passage extending-through the fountain to the heat ing chamber, said neck also having an open-- ing to said inletchamber, and a valve pivv uding a vessel, a de 'the'top of said fountain and c ose said fountain having a top forming one wall ofan insulating chamber, a neck rising from said top, a ca neck and forming the top of a valve chain- 'ber within the neck, a fountain tube rising from said cap, a tube extending through, said fountain and forming-a passage between the heating chamber-and said valve chamber,a diaphragm extending across the removably secured to the neck and dividing its interior into said valve chamber and into a lower inlet chamber, the

said diaphragm having an opening to the inlet chamber, and an opening to said passage, and a valve'pivotall mounted on said diaphragm to control ow through the opening to the inlet chamber, said neck hav ing an opening through its side wall to said inlet chamber. v-
